Yes, I have, as I have young children and need to raise them somewhere more humane than the US. Portugal and Spain were the options, and Spain was what we preferred after living in both.
I am not ignorant of the cost you surface wrt taxes, but taking into account my total US tax burden when you add in insurance and medical expenses for a family of four, cross jurisdiction tax credits for taxes I would pay in Spain, as well as the improved quality of life around work life balance, life pace, safety of living a car free life (walking or riding bicycles primary for transportation), and so on, it is a net positive for our situation. I admit others must perform their own assessment to understand if a potentially favorable outcome awaits them.
If you want to grind and become wealthy, it’s not the place to be; it’s a place to live. As always, be mindful what you’re optimizing for.
Ah, the complaint is merely about the taxes being high? Meh, I like to have infrastructure that doesn't fall apart + healthcare available for everyone, so hard to complain about it. It's just money after all.
(For what it's worth, I barely worked professionally in Sweden so I wasn't really used to anything tax related before I moved to Spain, but it probably colored my perspective, yeah)
To be fair I compare Spain to Switzerland where I currently live and other than the weather and maybe the mentality everything my tax money would be used for is argueable worse than here but costs 3-4 times as much.
(I didn't really earn money before I lived in Switzerland either. It's hard to imagine switching from maybe 13% tax on my income to 50% plus wealth tax)
The taxes are outrageous.
LE: Your income tax is ~47% over 60k/yr just so everyone knows what we’re talking about.
